摘要: 探寻水敏指数变化规律,可有效指导油田开发调整方案.作者通过统计文南油田的水敏试验资料,找出了水敏指数与岩石空气渗透率和注入水矿化度的关系.结果表明,其关系式相关程度很高,利用该式可预测这一地区不同岩石、不同注入水的潜在水敏性.该方法对其它油田或其它方面实验资料的应用具有重要的借鉴作用.

Abstract: The study of water sensitive indexes may effectively influence development of an oil field.By comparing the experimental data of water sensitivity in Wennan oil field,a relationship among water sensitive indexes,rock air permeability and salinity of injected water was set up.It is showed that there was very high level of association with each other.The relational expression can be used to predict the possible water sensitivity of different rocks and different injected water in the area.It may also have some indication for other oil fields during waterflood development.

- injected water salinity /
